Memento posted:When the Apollo missions were going up to space, they didn't have the toilets figured out yet so they pooped in bags. The bags were treated with antibacterial gel inside to prevent the poop from forming gases and exploding the poop bags. After they pooped, they would have to massage the bag for about five minutes so that the poop was thoroughly mixed in with the gel. the floating turd transcripts are gold. "it ain't one of mine!"

I'm pretty sure I've seen old Ladas loaded with more than a dozen Roma in Slovakia back in the late 80's/early 90's. And possibly some livestock.

Right on topic, check out Harold McCluskey, survivor of a plutonium accident at Hanford in the 70's and often called the most irradiated man alive or something. He was working in a glove box which exploded and embedded radioactive glass and Americium into his body. He lived for quite a while after.

GD_American posted:Isn't plutonium so unbelievable toxic that the radiative effects don't even have to come into play to (eventually, down the road) kill them? I believe the primary concern is that Pu is a good alpha emitter, which means it spews heavy particles at (relatively) low speeds, which wreck the poo poo out of the insides of people when ingested. Great, so don't eat Plutonium you say. The usual uptake of alpha emitters happens via breathing and accidental ingestion of airborne particles. Bad stuff. Anyone starting work at the Hanford site is required to undergo a whole-body count, which just determines the base activity of your body before you start working there. You get another one at the end of your employment contract. The process takes 20-60 minutes, depending on the precise scan performed. The scans are performed in giant copper chambers with ~1.5 ft walls made from pre-1945 copper. It's very quiet in there. If uptake of alpha emitters is suspected, the first step is to poo poo in a bag and submit it for examination. TotalLossBrain fucked around with this message at 23:24 on Mar 9, 2021 |

I highly recommend LANL's "A Review Of Criticality Accidents" which covers a lot of ground. Most of it is from Russia, a couple in Japan, and a bunch at US facilities. Going back to the picture Plutonium rods being placed too closely to one another - there was an accident with a Plutonium solution at LANL in 1958 that blasted a worker with an estimated 13,000 REM. Too much solution was put into a tank and when the worker peeked through a porthole-style window in the tank and started the stirrer, it flashed blue. Ooops.

Let's talk about what that "liquid processing waste" leftover from Plutonium production actually is (what Mayak dumped in rivers/lakes and Hanford still has in underground tanks). The very basics of Pu production: Fuel a reactor with Uranium fuel rods and turn it on. The reactions will produce Pu somewhere down the chain. Leave the rods in the reactor for about a month, and maybe 4-5% of the original fuel is now Pu. Then the irradiated, absolutely deadly radioactive fuel rods are pulled from the reactor and dissolved in nitric acid. That liquid is can be processed in a few different ways to get the Plutonium out of solution (though I think the PUrEx process is the most current one?). The other 95% of screaming hot liquid fuel rod is now "liquid processing waste". LOL Hanford also has had at least one self-boiling underground tank, but it's since been pumped empty. A lot of tanks have to be actively ventilated at all times. I worked on the Hanford Waste Processing plant over a decade ago. The rad zones inside the HLW processing canyon were marked 300,000 Rad  The leftover waste at Hanford is incredibly complex. Over 1,200 organic compounds have been identified. Waste characterization is its own job discipline out there and at the National Lab right next to Hanford. There have been a bunch of venting events at the underground tank farms over the decades where workers smell weird poo poo outside and get sick. I worked with a health-physics tech on site at the time and he would routinely tell me that all the radiation in the world wasn't scary to him because it could be measured easily and reliably. He was much more concerned about unknown, uncharacterized chemicals with no way of detection. It gave me some perspective I guess. Management loves to just call that bullshit, but they've started paying more attention ~2000 or so. TotalLossBrain fucked around with this message at 16:54 on Mar 11, 2021 |

I'll mention my weird experiences with the railroad here. I do research work that involves energy and transportation sectors. Each sector and industry has its own feel and character. It's extremely easy to obtain all sorts of information, software, firmware, used or new devices in the electric grid sector and general industrial automation. Vendor reps are easy to talk to, want to sell you stuff, and share information. It gets quite a bit harder in the oil and gas sector. You can still buy stuff and speak to vendors but obtaining information from operators gets a lot harder. These guys try to protect their infrastructure and are generally suspicious. And then there is the railroad sector. It's the single most walled off garden I've ever seen. Railroad operators won't even answer calls or emails. Vendors - if you can find out who they are - are extremely uncooperative. They might talk to you briefly just to tell you to gently caress off. Hardly any will even consider selling anything to anyone but railroad operators. There are very few vendors, they are tightly inter-linked and they all talk to each other. In conclusion, railroad opsec is pretty good

The Lone Badger posted:Will a properly-shielded isotope source still show up on roadside radiation detectors? Depends on how well it is shielded. The Radiation Portal Monitors DOE commissioned after 9/11 and distributed nationwide and even globally are sensitive enough to pick up shipments of bananas and even granite. Those are typically considered spurious/nuisance alarms and get calibrated out.
